为了完善煤炭产业链延伸发展战略,本文以P煤业集团2005年1月到2010年12月之间收入、利润、生产以及销售成本等四项财务数据的时间序列为基础,运用协整分析与系统仿真分析方法说明该集团五个产业子系统之间的引导关系及其稳定性。结果表明,收入、利润、生产以及销售成本等四项财务指标可以体现相应的产业引导关系,通过收入等财务指标的仿真分析可以说明产业之间引导关系的稳定性。依据产业之间的引导关系规律制定相应发展战略,能有效提升产业发展的可持续性。
In order to improve the strategy of extending the coal industry chain, based on the time series of four financial data of P Coal Group from January 2005 to December 2010, such as revenue, profit, production and cost of sales, the paper uses cointegration analysis and The system simulation analysis method shows the guiding relationship and stability between the five industrial sub-systems of the group. The results show that the four financial indicators such as income, profit, production and cost of sales can reflect the corresponding guiding relationship between industries. Through the simulation analysis of financial indicators such as income, the stability of the guiding relationship between industries can be illustrated. The development of corresponding development strategies based on the guiding relationship between industries can effectively enhance the sustainability of industrial development.
